Patented Nov. 18, 1930 UNITED STATES PATENT OFFICE FRANK STAINES, OF LONDON, ENGLAND DEVICE FOR CLEANING AND WASHING CROCKERY we ran LIKE Application filed octobe r 4, 1927, Serial No. 223,s94, and in Great Britain N vemb r s, 1926. I

This invention relates to devices for cleaning and washing crockeryvof thekind in which the articles, plates for example, are subjected whilst immersed in the cleaning liquid tothe action of rotary brushes arranged upon spindles disposed'one upon each side of the plate and in planes parallel to the The present invention hasfor its object to provide a device of the general typeabove referred to designed to secure the morerapid and effective cleaning of the articles.

According to this invention the articles to be Washed are subjected to the action of r0;

formed of india-rubber'or other flexible material disposed 'at a rightangle to the plate' and so arranged as to act simultaneously upon the front and back ofthe article, said plate during the operation of the discs being caused to rotate at a speed preferablyequal to the speed of the cleaning bodies, and preferably also the plate has a reciprocatory motion transversely of the said cleaning bodies or said ClGZIIllIlg bOdlBS or the effective surfaces thereof reciprocate transversely of said plate.

Preferably the cleaning bodies are arranged in two series respectively disposed upon spindles arrangedone on ea'chjside'of the plate, and they are of such diameter that their edges normallyoverlap. The bodies are arranged in spaced relationship on'efto another, those of one series being staggered with respect to the other, so that when ,nolplate is between them their outer edges 'do not con tact, Whenhowever a plate is in position the edges ofthe discs contactotherewith and are turned over so that a substantially broad S111- faceis acting upon theplate.

here the rotary bodies are in theforin of brushes the brushes. of one'series may be in the same plane as the brushes of thef other series, the bristles interengaging when no flaps recesses or chambers which act as suckarticle is between them, I a

In the preferred form where discs are employed the said discs are cut to formula 'num ber of flaps, and, in-or'der. to secure a certain cohesion of the "surfacesthereof with the plate, there are formed in the sides of the thewhole surface of the plate islacted upon. tary bodies in the form of brushes or discs,

013 the like, theymay be-so mounted that they are; inclined with respect to the spindle sup- 7 ers and cause the flaps to adhere more or less at a-i'ight angle to its axis. 7 Insteadof mounting'the disc as just described, adisc maybe employed provided with a cam surface adapted to secure the desired rnovern'entof the plate ,o v

; Instead of reciprocating eachseries ofdiscs portingthem; In order to retain the plate in position betweenthe cleaning devices, a roller orrollers isor are'provided so disposed as to engage the edge ofthe plate at a point or 80 points such as will give the plate a tendency tofall inwards; Preferably the. roller or V rollers isor are covered with .india-rubber or other material sofas to avoid damage tothe plate, said surface being ribbed, scored (or 85 otherwise treated to cngagethe edge-ofjthe I plate and retainsame in a vertical orsubstaln tially Vertical position. In rinsing the' plates- L they maybe placed between the cleaning bodies; 7 7 s The :rotary'bodies may be arranged'with their axes either in the horizontal or vertical 7 f planes.- v

The spindles 9, 10 Carry the cleaning discs whiclrin the form shown inthe figures referred to comprise an annular body'll, Figs. 1-7 and 10, preferablyformed of metal. Running transversely of the body a re channels 12 the inner ends of which are shaped as shown whereby there is provided I an enlargement also running transversely of the body 11. i

The cleaning elements a reformedof strips of india rubberl3 having a bulbous ezitrenr Figs. 7, 9 and 10,'adaptedto lit tightly within the enlargement at theinner end of the aforesaid channels 12.. Bythis means the strips 13 are held against displacement under I the action of centrifugal force and are also enabled to res st the drag upon them as they are drawniover the article. In order to increaseftheehect ofthe strips they are provided upon thesurface contactii g with the article with recesses whereby they are caused 'by suctlon to adhere closely to the surface to which they are applied, with tie result that not only is their cleaning action considerably enhanced, but by reason of their adhesion they more closely fol ow the outline of the surface to wh ch they are applied as for instance the curved surfaces at the edge of the plate.

The actionof the strips will be readily nn' derstood in reference to. Fig. 10 where it will be seen that as the ends of the strips contact with the front surface of plate 2 they bender turn over so that there is a surface of comparatively large area ing upon sa d said disc.

In the arrangement shown in l and 2 the cleaning discs acting upon the back of the plate are in the form. of discs of indiarubber 1.4 out as shown more clearly in F 3 and at, whereby there are provided a series of tongues 14E which, as they engage the sur face of the plate, are turned over so that the sides thereof act upon. the plate, as shown moreclearly in Fig. '4. The surfaces contacting' with the plates may be provided with I recesses such as thosev a: before referred to.

it runsout of truth and acts as a swashplate, and with which dlsc the lnner edge of the plate, which is supported by means of the roller 16 also having a rubber face, contacts." Preferably the surface of the rolleris grooved, the groove tending to maintain the [plate upright.

As shownthe cleaning members are so arranged that, they'act substantially upon one third-of the plate and underthe action ofsaid'members andfthe disc 15the plate is caused to rotat,e,the disc 15 during its rotation causing the plate to move backwards and forwards whereby the whole surface is acted upon, without however the, cleaning 'm'emb'ers'passmg beyond the centre of the plate, in which case the plate would cease to rotate or only rotateintermittently, as the action of the cleaning members upon one side ofthe, centre wouldto a great extent 1 nullify or reducethe driving action of those upon the other side.

Instead of iiounting the disc 15 in the Imanner described it may. be PIOViClGflllPOIf itsface with oneior'more cam surfaces or projections. whereby the desired-to and. fro vmovement ofthe plate is secured. The plate is held in contact withthe disc partly by its own weight, the position of the roller 16 beingsuchthat the plate naturally tendsto fall inwards towards thesaid disc 15; and

partly by the action of the cleaning members the direction of rotation of which is such that the Preferably the outer diameter of the cleaning members variestowards the outer edge of the'plate. Instead of formingone of the cleaning membersof strips of indiarubber both may be of disc form as shown in Figs; 3 and 4.

Instead, of arranging for the reciprocal mot on of the plate'to be effectedby means of pa swash-plate, the cleaning members plate tends. to rolltowards the themselves may be so set upon their spindles that they are inclined with respect: thereto. A disc having a small throwmay under these-circumstances be substitutedfor the swash-plate or the said swash-plate be arranged to give a comparatively slight movement only to the plate being washed;

An arrangement such as that just referred to is shown in Figs. and 6 where inclicates a swash-plate having a comparatively small throw. j The rotarybodies may be arranged with their axes in the vertical plane.

'lVhilst in practice very effective results are secured with discs such as those before described it may, where the cleaning-liquid is liable 'to contain a considerable amount of grease, be preferable 'to'employ brushes 2. A device for washing crockery and the.
